bar-chart[width] sp rescale the kets in sp to width, and then draw a basic bar-chart. a nice quick visualization of ket coefficients often combined with a sort operator of some sort
-- simplest example is a bar-chart of a Gaussian: bar-chart[50] Gaussian[0.7] |x: 10> ---------- x: 6 : | x: 7 : || x: 8 : |||||| x: 9 : |||||||||||||||||| x: 10 : |||||||||||||||||||||||||||||||||||||||||||||||||| x: 11 : |||||||||||||||||| x: 12 : |||||| x: 13 : || x: 14 : | ----------
